【技术问题】【technical problem】
当通过指纹验证来唤醒或解锁电子设备时，即使当电子设备处于睡眠状态时，包括在电子设备中的指纹传感器也可能需要处于唤醒状态。在这种情况下，由于指纹传感器的驱动可能消耗不必要的电力，并且电子设备的性能可能劣化。另外，当指纹传感器是光学指纹传感器时，由于显示器需要操作以提供用于指纹传感器的操作的光源，因此可能增加不必要的电力消耗。此外，即使当不包含指纹的另一个对象与指纹传感器接触时，包括在电子设备中的处理器也需要执行比较操作，从而导致不必要的电力消耗的进一步增加。When waking up or unlocking an electronic device through fingerprint authentication, a fingerprint sensor included in the electronic device may need to be in an awake state even when the electronic device is in a sleep state. In this case, unnecessary power may be consumed due to driving of the fingerprint sensor, and performance of the electronic device may be degraded. In addition, when the fingerprint sensor is an optical fingerprint sensor, since the display needs to operate to provide a light source for the operation of the fingerprint sensor, unnecessary power consumption may be increased. Furthermore, even when another object that does not contain a fingerprint comes into contact with the fingerprint sensor, a processor included in the electronic device needs to perform a comparison operation, resulting in further increase of unnecessary power consumption.

For example, display circuit 640 (eg, using BL IC 741 in display circuit 740 ) may drive display panel 630 (eg, display panel 730 ) such that at least a portion of display panel 630 (eg, display panel 730 ) emits light.
根据一个实施例，处理器660(例如处理器760)可以在显示电路640(例如显示电路740)操作时将控制信号发送到显示电路640(例如显示电路740)(3)。在显示电路640(例如显示电路740使用BL IC 741或DDI 742)驱动显示板630(例如显示板730)时，处理器660可以在各种情况下(例如为：当接收到呼叫时、当接收到消息时、当生成通知时、当操作定时器时或者当发生用户唤醒时)将用于控制显示电路640(例如显示电路740)的控制信号发送到显示电路640(例如显示电路740)，使得显示板630的至少部分区域(例如显示板730)发出光以用于指纹识别。According to one embodiment, the processor 660 (eg, the processor 760 ) may send control signals to the display circuit 640 (eg, the display circuit 740 ) when the display circuit 640 (eg, the display circuit 740 ) is operating (3). When the display circuit 640 (for example, the display circuit 740 uses the BL IC 741 or the DDI 742) drives the display board 630 (for example, the display board 730), the processor 660 may be in various situations (for example: when a call is received, when a call is received, A control signal for controlling the display circuit 640 (e.g., the display circuit 740) is sent to the display circuit 640 (e.g., the display circuit 740) when a message is received, when a notification is generated, when a timer is operated, or when a user wake-up occurs, such that At least a partial area of the display panel 630 (for example, the display panel 730 ) emits light for fingerprint identification.
根据一个实施例，在执行由触摸IC 620(例如触摸IC 720)请求的操作时，当从处理器660(例如，处理器760或能够向显示电路发送控制信号的另一模块(例如PMIC 670或770))接收到另一请求时，显示电路640(例如显示电路740或BLIC 741)可以将表示忙碌状态的信号发送到处理器660(例如处理器760或另一模块(例如PMIC 670或770))(4)。例如，显示电路640(例如显示电路740或BL IC 741)在根据从触摸IC 620(例如触摸IC 720)接收到的控制信号驱动显示板630(例如显示板730)时，当从处理器660(例如处理器760或另一模块(例如PMIC 670或770))接收到控制信号时，其可以将表示忙碌状态的信号发送到处理器660(例如处理器760或另一模块(例如PMIC 670或770))，以防止竞争状况。According to one embodiment, when performing an operation requested by the touch IC 620 (such as the touch IC 720), when the slave processor 660 (such as the processor 760 or another module capable of sending a control signal to the display circuit (such as the PMIC 670 or 770)) When another request is received, display circuit 640 (e.g., display circuit 740 or BLIC 741) may send a signal representing a busy state to processor 660 (e.g., processor 760 or another module (e.g., PMIC 670 or 770) )(4). For example, when the display circuit 640 (such as the display circuit 740 or the BL IC 741) drives the display board 630 (such as the display board 730) according to the control signal received from the touch IC 620 (such as the touch IC 720), when the processor 660 (such as For example, when the processor 760 or another module (such as the PMIC 670 or 770) receives a control signal, it may send a signal representing a busy state to the processor 660 (such as the processor 760 or another module (such as the PMIC 670 or 770) )) to prevent race conditions.
根据一个实施例，当接收到指示忙碌状态的信号时，处理器660(例如处理器760或另一模块(例如PMIC 670或770))可以在等待之后重新发送控制信号(5)。例如，处理器660(例如处理器760或另一模块(例如PMIC 670或770))可以等待使用如下代码：According to one embodiment, when receiving a signal indicating a busy state, the processor 660 (such as the processor 760 or another module (such as the PMIC 670 or 770)) may resend the control signal after waiting (5). For example, processor 660 (such as processor 760 or another module (such as PMIC 670 or 770)) may wait to use code like:
当(dsi_read(DDI_BUSY)＝＝DDI_BUSY){when(dsi_read(DDI_BUSY)==DDI_BUSY){
mdelay(10)；mdelay(10);
}}
display_init_sequence()；display_init_sequence();
例如，当显示电路640或740(例如DDI或BLIC)处于忙碌状态时处理器660或760可等待10毫秒然后重新确定显示电路640是否处于忙碌状态。处理器660可以每10毫秒重复执行上述操作。当显示电路640的忙碌状态终止时，处理器660可以重新发送用于驱动显示电路640的控制信号。For example, when the display circuit 640 or 740 (eg, DDI or BLIC) is in the busy state, the processor 660 or 760 may wait for 10 milliseconds and then re-determine whether the display circuit 640 is in the busy state. The processor 660 may repeatedly perform the above operations every 10 milliseconds. When the busy state of the display circuit 640 is terminated, the processor 660 may resend the control signal for driving the display circuit 640 .
根据一个实施例，处理器660可以以类似于上述方式的方式来控制发送用于获得指纹信息的源的其他模块，诸如IR二极管模块、超声模块或压电模块。According to one embodiment, the processor 660 may control other modules transmitting sources for obtaining fingerprint information, such as IR diode modules, ultrasonic modules or piezoelectric modules, in a manner similar to that described above.
